I saw the following two items in a branch in one of the largest pet supply chains in Germany, which typically have a decent and larger saltwater area.
The video contains both, an in tank light (which I have not seen anyone doing before), and the new Tunze coral rotational rock structure.
For the record, I do not believe either of them is a good idea, but I thought it was still interesting enough to share (sorry, I did not have a blue light filter with me on this day)
Price for the Tunze product.
